Match the List-I and List-II and select the correct answer from the codes given below :
| List I | List II |
|---|---|
| (a) Lithosere | (1) Water |
| (b) Psammosere | (2) Rock |
| (c) Xerosere | (3) Sand |
| (d) Hydrosere | (4) Dry region |
Codes : (a) (b) (c) (d)
Answer: D
The correct matching is (2) (3) (4) (1).
A sere is the series of communities in an ecological succession, and its prefix names the starting substrate:
- Lithosere begins on bare rock (Greek lithos).
- Psammosere begins on sand (psammos), as on coastal dunes.
- Xerosere begins in a dry region (xeros).
- Hydrosere begins in water (hydor), such as a pond.
Option A pairs psammosere with dry region and xerosere with sand, the commonest slip; options B and C misplace lithosere.
